I feel like my life has been taken away from me

Instead of enjoying my freshman year of college , i am married and having a baby while overseas. I thought this was the right decision at first because I’m married to a very good man and he’d do anything for me. I just found out he had sex 2 women in the very very beginning in our relationship , while we were together. I wish i would’ve known , then we would’ve broke up and i wouldn’t be pregnant. I wish i would’ve known, so i wouldn’t be married to him. I feel so fucking stupid i feel so naive i feel so stupid. He’s such a good person to me he would do anything for me why would he put me in this position. Why did he wait until i was pregnant and we were married to tell me. Why i do feel stuck. I feel so depressed
